Soil Analysis

Our soil analysis will help you determine your preplant and sidedress fertilizer requirements. It will also give you an understanding of the crop production capabilities of each field in terms of salinity, soil type, water holding capacity and percolation. Our standard soil analysis is for nitrogen, phosphate, salinity and water holding capacity. Analysis of other elements can be provided upon request.

Plant Analysis

During the growing season of your crops, we will sample and analyze plant tissue for nitrogen levels and other nutrients as necessary. By chemical analysis of the plant tissue, monitored on a timely basis, the nutrient status of the plants is determined and a fertilizer program is designed to supply the needs of each field and crop without excessive fertilization. Following each plant sample, a computer-generated graph is printed to show the nitrogen levels during the term of the crop, along with the growing history of your actual fertilizations, irrigation, prior fertilizer recommendations and weekly heat units. The graphs for many crops display ideal levels of nitrogen according to plant growth stage throughout the crop season.
